We want to create a "Request" library using Infopath and Sharepoint that allows users to fill out a form and submit it to the site, while preventing them from changing any existing forms. These certainly seems simple enough, but I don't know how to set the Sharepoint permissions to do this. I've tried using the custom rights "View Items" and "Add Items", but I still get an error when submitting a form.
Has anyone else done this seemingly simple task?
